We may be splitting hairs here, but a whole house circuit breaker is not what TLS Guy and others are referring to when they speak of whole home power conditioning/surge protection etc at the service entrance. If you are unsure if lightning struck your home, or simply struck nearby somewhere, odds are very good it didn't strike your home. If your home took a direct strike, as Chris Farley once so eloquently stated "oh, that's gonna leave a mark".
I'm going to leave your insurance story for others.
